As requested by viewers, I'm uploading my personal interface. It was tailored to my personal perception of information on the game screen, but perhaps some of you might find it convenient to use. This interface was made with a big screen in mind with people mostly looking at the center-bottom of the screen without much eye movement to the top/top-left/top-right.

Skillbars are concentrated in the middle bottom for a quick comprehension of which ones of them are on cooldown.

Target of target is located above the ops (party) frame for an ease of access by clicking if, for any reason, your keybind is out of reach.

It is important to use "dispay group as an ops frame" option from the SWTOR settings.
